Best time to travel to San Diego

San Diego is a year-round destination with mild weather, but the best times to visit are spring (March to May) and fall (September to November) when the weather is pleasant, crowds are lighter, and hotel prices are more affordable. Summer brings vibrant beach scenes and festivals, while winter offers a quieter coastal escape with plenty of sunshine.


Getting from SAN to San Diego and nearby areas

San Diego International Airport sits just about three miles north of downtown, making it one of the most conveniently located major airports in the country. Taxis and rideshare services like Uber and Lyft are available at the Transportation Plazas across from Terminals 1 and 2, and typically reach downtown in 10 to 20 minutes depending on traffic, with taxi fares running roughly $24 to $30. If you ride with Lyft, you can earn Atmos Rewards points on every trip—2 points per $1 on standard rides and 3 points per $1 on airport and premium rides—when you link your Atmos Rewards and Lyft accounts and select Atmos as your active rewards partner. For budget-conscious travelers, MTS Route 992 runs frequently between the airport and downtown, connecting to the Santa Fe Depot for Amtrak, COASTER, and trolley service. The free San Diego Flyer electric shuttle links both terminals with the Old Town Transit Center, while rental cars are served by free 24/7 shuttles to the Rental Car Center. Shared and private shuttle vans round out the options, making it easy to reach destinations across the region, from La Jolla and Coronado to Del Mar and Carlsbad.
